HOSPITAL BED.

To all Iwhom t may concern.'

Be it known that l, AGNES R. LENZ, a citizen of the United States, and a resident. of Huntley, county of McHenry, and State of illinois, have invented certain new and useful Improvements in Hospital Beds, of which the following is a speciication.

iwy invention relates to hospital beds and it has for its principal object the provision of a new Aand improved forni and arrange- 'mentby'which a ready 'adjustment can be made of the bed proper to suit the needs of the patient. and by which a. suitabie place for a nurse to rest is provided. Other objects will appear hereinafter.

The` invention consists in the combination and arrangements of parts hereinafter described and claimed.

Theinvention will be` best understood by reference to the accompanying drawings formingV a part of this speciiication, and in which,

Fig. .1 is an end view of my improved bed, showing in dotted lines the nurses bed in extended position; i

Fig. 2 is a side view of the bed shown in Fig. las seen from the right in said ligure;

Fig. 3 is top plan view of my bed, nartly broken away for clearness of illustration:

Fig. 3a is an enlarged detail wlew, being a fragmentary view as seen at the line 3 in Fig. L1- is a vertical cross section, being an inside f ce view of the end portion of the frame of the nursesr bed, a supporting leg i for such frame being 'shown in changed position in dotted lines;

Fig. 4 is a vertical cross section taken on line 4ta-4:3 in Fig. d; Y

Fig. 5 is a view, partly in section, showing the crank means for operating the supporting legs of the nurses bed; l

Fig. G is a fragmentary view, part in section, as taken on lines 6 6 of Fig. 5;

Fig. 7 is an enlarged detail view as taken on line 7 7 of Fig. 3;

Fig. 8 is a view of the part shown in Fig. T as seen from the right in said figure;- and Fig. 9 is an enlargedl detail view., being a cross section takenY on line 9 9 of Fig. 3.

Referring to the drawings, 15 indicates a bedstead of any approved type having the frame of a spring-bed mountedor resting upon its horizontal bars.` TheV spring-bed in the construction shown comprises angle barsV 16 mounted upon the upper ends of Specification of Letters Patent.

standards 17 which` in turn are mounted rigidly in positionA ufpon longitudinally extended bars 18. Reticulated supporting fahric 19 of any approved type is mounted between the cross-bars 16, springs 2O being interposed in the usual manner.

As is best shown in Fig.- 2, there are longitudinally extending strips at opposite sides of the supporting fabric 19. Pivotally mounted upon thestrips'21 upon a transverse axis, there are 'longitudinally extending auxiliary frame'ba-rs orstrips 22 which are connected at-their ends by an angle iron Reticulated supporting 'fabric 24 is mounted between the bars or strips 22, being connected' to the cross bar 23 by means of `springs 25 corresponding to the springs 20 above referred to. ln the preferred construction, the reticulated supporting fabric is formed of wires 'extending longitudinally and transversely in'spaced relation. As is shown in Fig. 3Q, the longitudinally extending wires of the supporting fabric 24 are connected tofone of the transversely extending wires of the'fabric 19 by having their end portions coiled thereabout, the reticulated fabric. 241 being thus pivotally connectedV with the reticulated supporting 'fabric 19. As is clearly shown in Fig. 2, mattresses 2G and 27 are laid upon the supporting fabric, the mattress 26 resting upon the supporting fabric 19 and the mattress 27 be.- iug supported by the fabric 24.

Means is provided for supporting the auxiliary' fra-ine and the supporting fabric carried thereby in elevated inclined position. ln the construction shown this means comprises arms 2S pivotally mounted at opposite sides of the framework, such arms being connected together bv a rock-shaft- 29. as is clearly shown in Fig. 3. In the construction shown', the arms 28 are formed integrally with the shaft 29, and eyes or handles 3() are also formed integrally with the arms for turning the arms about. the shaft 29; As is best shown in Fig. 7, the shaft 29 and the arms-28 formedA therewith are pivotally mounted upon the framework by mea-nsof clinps 31 of any approved type secured to the longitudinally extending strips 21. The arms 28 are effect-ive for supporting the auxiliary frame and the mattress 27 carried'thereby by reason of engagement with notches 32 formed in the bars or strips 22, as is best shown lin Fig. 2, the arrangement being such that the arms 2S may be moved in unison and be caused to engage the notches 32 b applying force to the eyes or handles 30. hen desired, the enga-gement between the arms 28 and notches can be easily andV quickly broken so as to permit the mattress 27 to move downward out of its inclined elevated'position. By the provision of a plurality of the notches-32, the mattress 27 is l capable of adjustment at the desired angle. n

y bed above described. Mounted upon the rods 33 so as to slide thereon, laterally with respect to the bed, there is an auxiliary frame comprising end bars 34 land longitudinally extending side barsV 35 connected to the end bars 34 Aby means of brackets 36. The means for mounting this auxiliary Vframe upon the rods33 comprises channel bars 37 connected in inverted position with the cross bars 34,' as is `best shown in Figs. 2 and4a. As is shown in Fig. 1, the bars 33 are inclined lslightly so aste permit the auxiliary `frame to slide easily into position beneath the supporting fabric 19 ofthe first described frame, a stop38 in the form ofY a collar and .a set-screw being provided upon the rod A33 for limiting the inward movement of the frame` thereon. lAs isrshown in Fig. 3, the auxiliary frame is provided with reticulated supporting fabric 39 of any approved type springs 40 being interposed between the edge of the fabric and the crossbars 34. A full length mattress 4l is supportedby the reticulated fabric 39 of the auxiliary frame.

Means is provided for supporting the vouter edge of the auxiliary bed when it is moved out so as to project laterally, as shown in dotted lines in Fig. l. This means comprises legs 42 pivotally mounted upon the cross bars 34 of the auxiliary frame, one of such legs being mounted at each end of the auxiliary frame. A longitudinally extending bar 43 is provided connecting the legs 42 at their lower end portions. As is best shown in Fig. 4, the legs 42 are adapted to be folded upwardly so as to project along the ycross bars 34 as shown in solid lines in said figure or seas to stand in vertical position as shown in dotted `lines in said figure. Means is-provided for moving the legs 42 into and out of supporting position and for holding them ineither of such changed positions.V This means comprises a pair of links 44 and'45 for each of the legs 42, such links being pivotally connected together by a pin 46 and having pivotal connection with the leg 42 and the crossbar 34. When-the links 44 and 45 are straightened outinto alignment with each other, the legs 42 are caused to stand in their vertical supporting position. When the legs are to be raised out of supporting position, links 44 land 45 are buckled upwardly with respect to each other, causing the legs'f42 to swing inwardly and upwardly into the position shown in solid lines in Fig. 4. The means for buckling the links 44 and 45 upwardly comprises a longitudinally extending rod 47 extending between the links 44. The rod 47 Vis provided with a bracket 4S mounted thereon for providing' a longitudinally extending slot 49, as is best shown in Fig. 6. In the construction shown the bracket 481is in the form of a heavy wire or rod having eyes 570 at its endstightly embracing the rod 47 4as is best shown in Fig. 5. A crank 5l extending between the side bars 35 of the auxiliary frame is provided, having a handle or lever 52by which it is adapted to be operated. As is best shown, in.- .Fig. 6, the offset portion 53 of the crank 51 has a working fit in theslot 49, whereby upon aV swinging motion of the crank the rod 47 is moved vertically with respect to the auxiliary frame. vAs the rod 4? is moved upward through thermedium ofthe crank 51, the links 44 between' which? the rod 47 is mounted are also moved up- \\.iardly, serving to carry the legs 42 out of supporting position, as above fdescribed. Releasable means is provided for holding the crank 5l in turned position for maintaining the legs 42 in their raised position. This means in the construction shown comprises a spring clip 54 fixedly mounted upon the side bar 35 of the auxiliary frame.'
